I've been using windows for 10 years, and now discovered Ubuntu, which is way cooler, but the downside is that I'm at a complete lost.. So far , so good but what I find annoying is that I have to type my password for every single thing I do, is there a way to disable that?

When you first get Ubuntu it can feel like this, especially because you're constantly installing/updating, relogging, restarting. But after you get to the point where you're just using it as your everyday machine this sensation passes.
